Radiation is the emission or transmission of energy in the form of waves or particles through space or a material medium.
A moving charged particle is a particle that has an electrical charge and is in motion.
The equation is F = q(E + v × B), where q is the charge of the particle, E is the electric field, v is the velocity of the particle, and B is the magnetic field.
The radiation term (qE) represents the force exerted on the particle by an external electric field, while the non-radiation term (qv × B) represents the force due to the particle's motion in a magnetic field.
Understanding these terms is important for predicting and manipulating the behavior of charged particles in different environments, such as in particle accelerators or in space. It also has practical applications in fields such as electronics and medical imaging.
